Diet and the Microbiome

The gut microbiome — a teeming mass of bacteria, fungi, viruses, archaea and protozoans that live in our lower gastrointestinal tracts — has captured the attention of health-conscious consumers. Through controlled studies with mice, scientists have learned that by manipulating the microbiome, we can induce weight loss, affect pain perception and decrease hormonal responses to stress, among other fascinating outcomes. We know that the microbiome interacts with the immune, neuroendocrine and cardiovascular systems to affect health.

Gut Check

Thousands of species of bacteria, viruses and fungi live on and in our bodies. Microorganisms teem in every pore and crevice, from mouth to stomach to intestines to colon.

A Poison in Small Doses

Thousands of wells in Bangladesh are contaminated with arsenic from groundwater aquifers. Oregon State University researchers are studying the health consequences of low-dose exposure in rural communities.

Climate Change and Health

As the world warms, insects and pathogens are on the move. Heat waves are getting hotter and more frequent. Algal blooms are increasing in frequency, intensity and duration, posing risks to drinking water and shellfish consumption. Wildfires are putting more particulates into the air, leading to increases in asthma and hospital admissions for respiratory distress.
